40. Behavior modification (not a term Skinner used) refers to the overall procedure of shaping student behavior intentionally through reinforcement.This procedure still comprises a major part of many teachers' discipline systems,. particularly at the primary grade level. Constant reinforcement, provided every time a student performs a desired act, helps new learnings become established. The teacher might praise Jonathan every time he raises his hand, or privately compliment Mary every time she turns in required homework.
41. Intermittent reinforcement, in which rewards are supplied only occasionally, is sufficient to maintain desired behavior once it has become established. After students have learned to come into the room and get immediately to work, the teacher will only occasionally need to express appreciation. Behaviors that are not reinforced soon disappear or, as Skinner said, become extinguished. If Roberto raises his hand in class but is never called on, he will sooner or later stop raising his hand
